How to Sharpen or Fix Broken Drill Bits

Over time, drill bits become dull and cease to cut effectively. Sharpening dull bits can improve the quality of your work, put less strain on your tools, and generally make drilling safer (since you can let the bit do the cutting, rather than applying force that can cause the bit to break). Sometimes, drill bits do break. You don't necessarily need to throw it out!

One option is to buy a Drill Doctor. These range from $50 for your Basic Drill Doctorto their $150 Professional Drill Bit Sharpener.

Here's an article on How to Sharpen Twist Drill Bits.

In addition to learning the correct angles, the article explains the three distinct motions one must use while holding the bit against the grinding wheel.

1 - Move the bit to the left (grinding on the left edge only)
2 - Rotate the bit in clockwise rotation
3 - Move the bit downward
